Use of Voriconazole to Successfully Treat Disseminated Trichosporon asahii Infection in a Patient with Acute Myeloid Leukaemia

Trichosporon spp. is an emerging fungal pathogen in immunocompromised hosts, and disseminated infection is often fatal in neutropenic patients. Reported here is a case of disseminated infection in a neutropenic patient with acute leukaemia. After failure of amphotericin B and fluconazole therapy, the course of infection dramatically improved with voriconazole treatment. A literature search revealed 69 additional cases of disseminated Trichosporon spp. infections in neutropenic patients, and these are also reviewed. Clinical symptoms that suggest infection include fever, disseminated papulopustular cutaneous lesions and pulmonary involvement. Despite treatment with antifungal agents (amphotericin B, fluconazole), 78% of patients died. Voriconazole may represent a promising therapy for this life-threatening infection.
